14、 the present document is to give an implementation guide to the relevant Common IMS specifications and functions used in the interconnection of a Next Generation Corporate Network site (NGCN site) to the Next Generation Network (NGN). The present document addresses control plane signalling (usage of

15、 SIP and SDP protocols, required SIP headers) as well as other interconnecting aspects like security, numbering/naming/addressing and user plane issues such as transport protocol, media and codecs actually covered in a widespread set of 3GPP and ETSI TISPAN specifications, as seen from the perspecti

16、ve of an NGCN site. Advice-of-charge aspects are addressed as far as SIP signalling is concerned. The present document is based on TS 124 229 Release 7 i.12 as modified by ES 283 003 Release 2 i.15. NOTE Some errors corrected in TS 124 229 Release 8 and 9 are already taken into account in the presen
